  To: Intel-gfx; +Cc: Rodrigo Vivi

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Currently to change the firmware one has to update the exported
module firmware string and the major-minor versions used for
verification after load. Consolidate that to a single place
defining correct major and minor versions per platform.

v2: Rebased for KBL.
